Question formats
CompTIA Advanced Security Practitioner (CASP+) CAS-004 is an advanced-level cybersecurity certification aimed at IT professionals who design and lead security solutions rather than manage policy. It covers security architecture, risk management, enterprise integration, research and collaboration, and cryptography at a deep technical level. Unlike management-focused certifications such as CISSP, CASP+ is hands-on and practitioner-oriented, validated through performance-based questions. It is DoD 8570/8140 compliant and is widely recognized in government and defence sectors.
Official prerequisite
None — CompTIA recommends but does not require prior certifications
Recommended experience
10+ years of IT administration including 5+ years of hands-on technical security experience; Security+, CySA+, or equivalent knowledge
Experienced security professionals with at least 10 years in IT and 5 years in security who want to validate advanced architecture and engineering skills
Should you skip this exam?
If you are new to security, start with Security+ or CySA+; if you want a management/governance cert instead, consider CISSP or CISM
Courseiva study tip
CASP+ requires synthesis across domains — do not rely on memorisation alone. Practise scenario-based labs and study cryptographic concepts and enterprise security architecture in depth

What certification to take next
The CAS-004 exam costs $494 USD per attempt. This is CompTIA's most expensive exam, reflecting its advanced level.
No — CASP+ is graded Pass/Fail. CompTIA does not publish a numerical passing score for this exam.
CASP+ is considered one of the hardest CompTIA exams. It is designed for senior practitioners with a decade of experience and tests applied judgment, not just recall.
The exam has a maximum of 90 questions, with a generous 165-minute time limit to accommodate complex performance-based items.
CASP+ tests security architecture, risk management, enterprise security integration, research and collaboration, and advanced cryptography. It is practitioner-level, not management-focused.
CASP+ is valid for 3 years. Renewal requires earning 75 CEUs within the 3-year cycle or passing a qualifying exam.
CASP+ is a hands-on, technical practitioner credential, while CISSP is managerial and policy-oriented. CASP+ suits engineers who design security solutions; CISSP suits those who manage and govern security programmes.

Sample questions
Select your answer before revealing the explanation. These questions are original exam-style — not copied from any exam or dump site.
Trap 1: It provides deep packet inspection to detect malicious traffic.
Deep packet inspection is a separate security function, not inherent to SDP.
Trap 2: It enforces multi-factor authentication for every session.
MFA can be added to both VPN and SDP; it is not unique to SDP.
Trap 3: It reduces latency by establishing direct peer-to-peer connections.
SDP often uses a broker to initiate connections, which may add latency compared to a persistent VPN tunnel.
It provides deep packet inspection to detect malicious traffic.
Why wrong: Deep packet inspection is a separate security function, not inherent to SDP.
It enforces multi-factor authentication for every session.
Why wrong: MFA can be added to both VPN and SDP; it is not unique to SDP.
It reduces latency by establishing direct peer-to-peer connections.
Why wrong: SDP often uses a broker to initiate connections, which may add latency compared to a persistent VPN tunnel.
It prevents unauthorized users from discovering the application infrastructure.
SDP uses a 'black cloud' approach where the application server is invisible until the user is authenticated and authorized, reducing the attack surface.
Trap 1: Apply Kubernetes network policies to restrict pod-to-pod…
Network policies control traffic flow but do not provide encryption or authentication.
Trap 2: Configure RPM package signing for all container images.
RPM signing is for binary packages, not container images; container images use image signing (e.g., Notary).
Deploy a TLS termination gateway (e.g., NGINX ingress) with certificate management.
Terminates external TLS and can re-encrypt internally; manages certificates for external-facing services.
Use Kubernetes Secrets mounted as volumes with integration to an external vault.
Kubernetes Secrets store sensitive data; integrating with an external vault ensures secure access and rotation.
Apply Kubernetes network policies to restrict pod-to-pod communication.
Why wrong: Network policies control traffic flow but do not provide encryption or authentication.
Implement a service mesh such as Istio to handle mTLS between pods.
Service mesh provides mutual TLS, authentication, and encryption between microservices.
Configure RPM package signing for all container images.
Why wrong: RPM signing is for binary packages, not container images; container images use image signing (e.g., Notary).
Trap 1: WPA2-Personal
WPA2-Personal uses PSK, not 802.1X.
Trap 2: WEP
WEP is insecure and does not support AES or 802.1X.
Trap 3: WPA3-Enterprise
WPA3-Enterprise uses GCMP-256, not AES-CCMP.
WPA2-Personal
Why wrong: WPA2-Personal uses PSK, not 802.1X.
WEP
Why wrong: WEP is insecure and does not support AES or 802.1X.
WPA3-Enterprise
Why wrong: WPA3-Enterprise uses GCMP-256, not AES-CCMP.
WPA2-Enterprise
WPA2-Enterprise with AES-CCMP and 802.1X meets all requirements.

The master key would be in the cloud KMS, not under the company's exclusive control.
Trap 2: Use server-side encryption with customer-provided keys (SSE-C).
The key is provided by the customer but still used by the cloud server; the cloud provider may have access to the key during encryption/decryption.
Trap 3: Use server-side encryption with cloud provider-managed keys…
The key is managed by the cloud provider, not the company's HSM.
Use envelope encryption where a cloud KMS wraps a data key, and the data key is used to encrypt the data.
Why wrong: The master key would be in the cloud KMS, not under the company's exclusive control.
Use server-side encryption with customer-provided keys (SSE-C).
Why wrong: The key is provided by the customer but still used by the cloud server; the cloud provider may have access to the key during encryption/decryption.
Use server-side encryption with cloud provider-managed keys (SSE-S3).
Why wrong: The key is managed by the cloud provider, not the company's HSM.
Use client-side encryption where the application encrypts data before sending it to the cloud.
The company controls the encryption key entirely on-premises; the cloud only stores ciphertext.

SD-WAN optimizes routing but does not provide granular per-component access control.
Trap 2: Use network ACLs on the cloud VPC and on-premises routers to deny…
Network ACLs are stateless and less granular than stateful firewalls; they do not track connection state.
Trap 3: Deploy a site-to-site VPN and route all inter-component traffic…
VPN concentrators create a trust boundary but do not enforce least privilege at the component level.
Deploy an SD-WAN with dynamic path selection and encryption for all inter-site traffic.
Why wrong: SD-WAN optimizes routing but does not provide granular per-component access control.
Implement micro-segmentation with stateful firewalls and explicit allow rules between each workload.
Micro-segmentation with explicit allow rules ensures only necessary traffic is permitted, adhering to least privilege.
Use network ACLs on the cloud VPC and on-premises routers to deny all traffic by default, then allow required ports.
Why wrong: Network ACLs are stateless and less granular than stateful firewalls; they do not track connection state.
Deploy a site-to-site VPN and route all inter-component traffic through a VPN concentrator.
Why wrong: VPN concentrators create a trust boundary but do not enforce least privilege at the component level.
Trap 1: Configure a site-to-site VPN from the corporate network to the ICS…
VPN would allow inbound connections, increasing risk.
Trap 2: Implement a network-based intrusion prevention system (IPS) on the…
IPS is reactive and may not prevent all unauthorized access.
Trap 3: Segment the networks using VLANs only
VLANs without additional controls can be bypassed.
Configure a site-to-site VPN from the corporate network to the ICS network
Why wrong: VPN would allow inbound connections, increasing risk.
Implement a network-based intrusion prevention system (IPS) on the ICS network
Why wrong: IPS is reactive and may not prevent all unauthorized access.
Deploy a unidirectional gateway (data diode) between the networks
Ensures traffic can only flow out, preventing inbound access.
Place a bastion host in a DMZ accessible from both networks for monitoring traffic
Allows necessary monitoring without exposing the ICS network directly.
Segment the networks using VLANs only
Why wrong: VLANs without additional controls can be bypassed.
